Folks, I now have my greenhouse in place, and my peppers, eggplants and even tomatoes overwintered beautifully. The entire structure is built from 100+ year old materials from dumpsters, basements, and sidewalks in our neighborhood in Atlanta, Georgia. Thanks to everyone who gave me tips, particularly the one who told me that I should build the largest greenhouse possible, since anything else would be too small very soon. They were right!

I have put together a slide show showing the construction process, and the final greenhouse. You can toggle the slideshow in the upper right to go quickly through all pics. Here it is - enjoy.

Wow dude very impressive. I toyed with the idea of making one similar to that myself but my carpentry skills are lacking in a big way and I was worried hail may cause damage and ruin it. I really like the look of it though and it makes me wish I had one. Are you in the pic of urban gardeners?

Nice, I have about 50 wood window panes and most of the materials for mine. Just need to find the time to build it. Mine will be off the back of the garage and have a roof slope similar to yours. I have some heavy plastic to use first couple seasons for the roof and see how that goes, then switch to the double walled panels from the local greenhouse supplier, but they are not cheap. Didn't get to look through all photos but what did you use for ventilation? What are some of the ways you plan on using it? Since my climate is similar to yours I was wondering what could possibly survive in there in June-August...

I had zero carpentry experience before I started. Lesson one- buy the best table saw you can afford. The table saw is the most important tool.

Lesson Two - buy a high torque battery screwdriver, such as the Milwaukee brand. High torque because you are driving three inch deck screws into lots of wood.

I am going to cover the top with one layer of 6 mm greenhouse transparent plastic so taht the water and leaves run off, rather than pooling and sticking in the windows. That won't affect the look at all, but will keep the top cleaner and in better condition.

Plastic alone would not work here in Atlanta because of the squirrel pressure. So I needed glass.

Ventilation: I have two windows in the ceiling that pop up on hinges, and a door and opening window in opposite walls. But I don't intend to use the greenhouse in summer - it is mostly shaded. It works as a greenhouse only when the leaves are off the trees, which is when I need it.
